So... in short, you can't use radiosity. (Unless it's on a scene where it
won't make any real difference anyway.)

Actually, I like the idea of using an area light instead. (There is a large
white object directly under the skylight that was supposed to throw the
light around the room - but it doesn't anyway!) I had actually noticed that
specular highlight doesn't work with radiosity. (I would have expected them
to work really, but I guess I can see why they doesn't.)

Any yes - that bit about "pastel shapes" was the fact that, for example, an
orange light like rgb <1, 0.5, 0> will come out yellow with ambient 10. (And
yet - I presume! - the room will be lit up orange, not yellow. Haven't
actually tried it mind you ;-)

Oh well, thanx anyway people!
Andrew.
